Question

Someone please help me on this problem??

Answer 1

Let
`x` be the unknown number. The sum of that number and two is
`x+2`. Ten times this sum is
`10(x+2)`. This must be equal to 300, so the equation is

`10(x+2) = 300`

To solve this equation, we can divide both sides by 10:

`x+2 = 30`

and subtract 2 from both side:

`x = 28`
